Referring to the drawinn's, the 11min frame lof the machine comprises a bed plate 10, adapted to be secured `upon n table or support, end an overhangine;v arm 1l rising` tromfand extending outwardly from the bed plate. y y

rlhe main driving` shaft l2 is journalled in a bearingl?) iformedby the arm llandn bearing 'le rising,1 'from the bed plate 10. The lshaft 19 is provided with n driving ypulley `l5 and a suitable clutch 16 'or contrice,

necting and disconnecting the pulley and shaft for starting and stopping the operation of the machine.

Secured to the outer end of the arm 11 is a shaft 17 which extends downwardly therefrom and fixedly supports a disc-like head 18.

Surrounding the head 18 and rotatably fitted 'to the periphery thereof is a ring 19 supported by a ring plate 20 which is secured to the bottom of the head 18. The ring 19 is provided with a circular series of radially-projecting impaling pins 21 for receiving the loops of the fabrics to be united and supporting and advancing them to the sewing mechanism hereinafter described.

The ring 19 is provided with internal gear teeth 22 in mesh with a pinion 23 arranged within an opening in one side of the head 18. The pinion 23 is secured to a vertical shaft 24 which is mounted to turn in a bearing in a bracket 25 secured on the head 18.

The upper end portion of the shaft 24 has a toothed wheel 26 keyed thereon; and, rotatably mounted on the wheel 26, is a worm wheel 27 which embraces and encloses the toothed wheel 26. The teeth of the wheel 26 correspond in number with the teeth of the worm wheel 27, and the worm wheel 27 has a vertical stem or pin 28 fitted to turn therein and provided on its lower end with a projection 29 forming a pawl adapted to engage any one of the teeth of the wheel 26 to cause it tobe turned by and with the worm wheel 27. The upper end portion of the stem 28 extends above the worm wheel 27 and is encircled by a spring 39 one end of which engages the worm wheel 27 and the other end of which engages a transverse pin 31 piojecting from the stem and tends to turn the pawl into operative engagement with the teeth of the wheel 26. The pawl 29 may be disengaged from the wheel 26 to permit it to be turned independently of the worm wheel 27, for a purpose hereinafter explained, by turning the stem 28 by hand against the action of the spring 30. rlrhe shaft 24 extends downwardly below the bottom of the head 18 and it is provided with a suitable handle or crank. 32 by means of which the shaft 24 may be operated to turn the impaling pin ring 19 by hand when the paw] 29 is disengaged from the wheel 26. The worm wheel 27 is in mesh with a worm on a supplemental driving shaft 34 fitted to turn in bearing 35 on the bracket 25 and a bearing 36 connected to the bed plate 19. rlhe supplementalshaft 34 is provided with a bevel gear wheel 37 which co-aets with a similar wheel 38 on the main driving shaft 12, whereby, when the driving shaft 12 is rotated, the ring 19 carrying the iinpaling pins 21 will be slowly and continuously revolved at a uniform speed.

The arm 11 of the main f 'ame of the machine carries a reciprocative support 39 formed by a casting having a cylindrical projection 40 fitted to slide longitudinally in bearing 41 formed by the arm 11. rllhe support 39 is prevented from turning about the axis of the projection 40 by a rod 42 projecting fixedly from the arm 11 parallel to the axis of the projection 40 and through a bearing 43 on the support 39. The support 39 is slidable on the rod 42 and its projection 40 is slidable in the bearing 41 and it is guided thereby in a manner to permit it to be reciprocated back and forth as will be presently explained.

The support 39 has a shaft 44 fixed thereto and extending therefrom and carrying a head 45 which is located beneath the supplemental driving shaft 34. The head 45 is provided with a post 46 carrying a bearing plate 47 having side flanges 48 embracing the post and pivoted thereto by a pin 49 which extends through the post 46 and flanges 48. The plate 47 rests against an adjusting screw 50 screwed into `and through the post 46 and it engages a :am 51 on the shaft 34 and is held against the same by a spring 52 encircling the rod 42 between the support 39 and an adjustable head 53 screwed on to the rod 42 land tending to move the support 39 and bearing plate 47 ;arried thereby toward the frame arm 11. During the rotation of the shaft 34, the cam 51 and spring 52 operate to reciprocate the frame for a purpose hereinafter described.

The curved needle 54 yand the curved looper 55 of the sewing mechanism and their supporting and guiding parts are carried bodily by the reciprocative support 39, and the needle and the looper are moved relatively to each other while being thus bodily reciprocated.

The needle 54 is carried by an arm 56 projecting from a collar 57 on a shaft 58 which is arranged parallel to the main driving shaft 12 and which is mounted to turn in the support 39, as clearly shown in the drawings. The needle 54 and shaft 58 are located with respect to the impaling pins 2l passing beneath them so that when the arm 56 is oscillated the needle 54 will be projected and retracted in a manner to cause its pointed free end portion to he projm-,ted over the impaling pins` and through the `grooves therein and through the loops of the fabrics carried thereby and to be retracted therefrom during the sewing operation. 'The collar 57 is provided with a projecting arm 59 having a crank pin 60 extending therefrom parallel to the shafts 12 and 58. The pin 60 is fitted to turn in one end of an arm 61 whose other end is provided with a strap 62 surrounding an eccentric 63 on the main driving shaft 1:2, whereby, when the shaft 12 is rotated, the

guiding groove in the outer portion of the member 92. The vertical portion 99 of the plate 98 has a vertical slot therein for the reception of a set screw 100 screwed into the member 92 to hold the plate 98 and stitch finger 97 in different positions of vertical adjustment. The stitch receiving finger 97 is arranged above the inner edge portion of the projection 98 and over and parallel to the path of the edges of the fabrics carried by the impaling pins 21 and the free end portion of the nger 97 projects over the path of the needle 54 and beyond the same in the direction of movement of the fabrics carried by the pins 21, whereby, during the sewing operation, stitches will be formed around the finger 97 and discharged from the free end thereof with or without the presence of the fabrics at the sewing point.

lhen the needle 54 penetrates the edges of the fabrics being sewed it tends to move the fabrics radially outward on the impaling pins 21 and maintain them in close relation to the edge of the projection 93 of the member 92 which serves as a stop or abutment, and7 I have discovered that by having the finger 97 bear a vfixed relation to the projection 93 and by permitting the linger 97 and projection 93 as a unit to yield outwardly against the spring 96 when the thickness of the edges of the fabrics being united varies, I am enabled to produce stitches having a marked degree of superiority as regards uniformity and evenness irrespective of such variations in the edges of the fabrics.

The operation of the machine is as fol lows:

`When power is applied to the driving shaft 12 the ring 19 and the impaling pins 21 carrying the loops of the edges of the fabrics to be united are -revolved continuously and at a uniform rate of speed in the direction of the arrow in Fig. 1; und the needle 54 and looper are oscillated by the eccentrics 68 and 687 respectively.

Each time the main driving shaft 12 and therewith the supplemental driving shaft -'l-lmakes one complete revolution, the ring 19 is advanced a distance equal to the distance between two adjacent impaling pins 2l: and each time the shaft 12 makes a complete revolution, the needle 54 and the looper 55 are each advanced and retracted to form a stitchV by the oscillations of their arrying arms 56 and GG1r respectively. An impaling pin 21 is thus presented to the needle 54 for each stitch forming operation.

During the formation of the stitches the needle 54 passes beneath the stitch receiving linger 97 and through the grooves in the impaling` pins 21 and through the loops of the fabrics carried by the impaling` pins,

G5 and the looper 55 passes back and forth over the linger 97 and the loops of the fabrics carried by the pins 21; and the needle and looper are arranged and operated relatively te each other so that the needle 54 will take a loop of looper thread 79 from the looper on one side of the edges of the fabrics and the looper 55 will take a loop of needle thread 78 from the needle on the other side of the edges of the fabrics and thereby form a chain of stitches around the linger 97 and through the loops of the fabrics while the fabrics are passing the sewing point, and form a chain of stitches around the linger 97 alone when no fabrics are present.

The needle 54 and looper 55 co-operate to form the stitches substantially in the same manner as the needle and looper shown and described in my previous Patent No. 1,069,- 336, co-operate to form stitches.

As the needle 54 is operated to produce stitches during the continuous movement of the .impaling pins2l, the cam 51 moves the needle 54 laterally against the action of the spring 52 at the speed and in the 4direction of movement of the impaling pins 21 passing beneath the same while the needle is actually engaged with the impaling pin or while it is being projected through and being with,- drawn from the loops of the fabrics carried by the pin. This occurs during about two thirds of the cycle of operation of the needle. During the remaining one-third of the cycle, and while the needle is clear of the impaling pins, the spring 52 is occupied in moving the needle 54 laterally in the reverse direction to meet the next succeeding impaling pin 21. It will thus be understood that the needle 54 will be moved back and forth laterally to meet and move with the impaling pins successively as they pass beneath the needle. The contour of the cam 51 such that the needle 54 will be moved slowly in the direction of movement of the in'ipaling pins in accurate registry therewith while working within the groove in one of the pins, and will be moved quickly back or in the reverse direction to meet the next sueceeding pin, during the relatively shfnft time that the needle 54 is clear of the inipaling pins. rlhe long portion a of the cam 51 moves the needle in the direction of movement of the pins 21 and the short portion 7) of the cam 51 permits the spring 52 to return the needle 54 Ato meet the next. suc-- cceding pin 21.

Should any knots be present in the loopsl of fabrics impaled upon the pins 2l. or should the fabrics carried by the pins be of uneven thickness, the presser member 92 will yield outwardly against the action of the spring 96 to accommodate the variations in the fabrics and permit them to pass between the ring 19 and the projection 93 without disturbing the relation of the finger 97 to the projection 937 resulting in the. productionvof elastic stitchesand ofthe uniform serving previously "referred to.

Should anyparts ofthe fabricsbeing united becomej am med` betvveen the impaling pins 2l. pand the i presser unember 92, i, the latter may be readilydepressed by hand against the action of the spring `96` `tor free the jainrnedparts. 1 v i `When it desired ,to-turn the. ring 1S) carryin `the impaling, pins `21 baclnvardly o-r forwardly relatively to `theneedle5l. for any desired `purpose Without operating the sewingvmechanism, the same may bexdone by disengaging the pawl `29 i from thel wheel tandoperating the cranlrBQto turn the shaft 24 by hand with the-needlewe Ein `a `positionretracted from the impaling,` pins It `will :be observed `thatjthe Worm B3 makes one complete revolution for each back and Aforth lateral ,movement-` of .the `needle andth'atthe same partjof the Worm `33 operates the Worm ivheelLQT. to move the; impaling pins forwardly duringeaoh time lthat the need-le is movingflaterally vv'iththe pins, and y that `anotherpbut alvvays 'the same; part ofthe Worm 33 operates thevworm Wheel27 toimoveithe,pins 2l^forivardly during' the baclmvardfor; reverse `lateral movement of the needle 54'. :It will also beobserved that this f relationship `betWf-ien `the fneedle 54E and the Worm 33'is preserved irrespective Vof the number `of times that ,the shaft ,A24 is ndisconnected'froin and turned relatively tothe Worm WheelEZ for` turning thering` 19 without u operating the sewing iinechanism.

i I have discovered thatvthe .preservation of this relationship `between thev'needle 54r- `and thefvvorm 33 `isimportant in preservingthe accuratefregistry lof the.needle-5lA with lthe pins 21 and their' proper.cofoperation during the `stitch forming! operations, particularly after some Wear has occurred-in the `operatingvparts ofthe machine.
